The Rock quickly accepted his challenge sharing a video in which he confirmed he’d donated his $25k.

He said: “Kevin Hart, you issued the Hurricane Harvey challenge, I appreciate you brother, I just donated my $25,000 to the Red Cross.

“I’m not going to call out my celebrity friends, you guys already know what to do in donating money.”

Bad boy rapper Chris Brown then pledged $100k (£77k) to the victims of the horror storm.

In his own video, he said: “What’s up big bro, Kevin Hart. I accept your challenge. We need to come together.

“I’m donating $100,000. So man, this is for everybody out there in Texas, the relief and everything. I accept the challenge and I implore and encourage everybody else, who can change and make a change for this, to please donate and help out. Love you all.”

DJ Khaled also responded with a 25,000-dollar (£19,000) pledge and Sean “Diddy” Combs pledged $25,000 praising Hart for his idea.
